FXS card for Communications Manager

[angel-moon]

Hello,

I have an FXS card going into a 1921 router.  I have documentation for the FXS card configuration on the router.  Can someone tell me where I need to configure this in CM?

Thanks,

That depends on CUCM version, and protocol to be used.

I believe its SIP on 10.5

Then in CUCM all you need is to configure a SIP trunk pointing to the GW and all the relevant call routing info (RP/RL/RG)

I'd personally go with H.323 or MGCP for old TDM interfaces and leave SIP for communication between other clusters, and SIP trunks to the PSTN, just my personal preference.
